I'm fairly suspicious of the -i switch you are using.  As a general
rule, you should NEVER use -i unless you have been told to by someone
who knows exactly what they are doing.  That safety check is there for
a reason.

Other than that, though, the only thought that comes to mind is that you
may be confused about the use of -C.  IIRC, specifying it at dump time
is useless --- it needs to be given to pg_restore instead.  You have
evidently got a non-empty (already restored into?) target database and
I think you are expecting pg_restore to clean it out, which it will not
with these command line options.
